Tracking Growth Matters ®️
The One Grows Digital Height/Length measuring device revolutionises conventional methods of measuring a person’s height .One Grows is the first to have a digital length /height measuring device that is BlueToothed to automatically record height/ length data on our own developed App, TRACKING GROWTH MATTERS®, solving transcription errors! It is accurate, precise, user friendly, convenient to use & engaging to the user.
Consider the profound implications of poor nutrition on physical, cognitive & developmental health, accurate anthropometric assessment is a crucial public health practice. Health surveillance works to ensure the early detection & treatment of stunting, wasting, & obesity. Height assessment is an essential metric.
The life science, educational fields & healthcare industry stand to benefit significantly from the revolutionary Digital Height Measure by One Grows. TRACKING GROWTH MATTERS®.
Research reports One Grows digital measure to be “Easier, Portable and Accurate”.
The latest research; Comparing the accuracy of an ultrasound height measurement device with a wooden measurement board among children aged 2-5 years in rural Lao People's Democratic Republic: A method- comparison study. By Shan Huang et al. November 2023. "Our study demonstrated the One Grows™ ultrasound device performs valid height measurements in standing children 2–5 years of age, and that the measurements were as accurate and precise as wooden measurement boards."
Frequently Asked Questions
Q. Is there an App provided by One Grows?
Yes. Tracking Growth Matters app developed by One Grows can be found in the Apple and Google Glay stores. It is free.
Q. What is so good about the Tracking Growth Matters App??
One Grows research found that height measurement is a critical variable for many health/ fitness assessments and accurate milestone records need to be reliable. Therefor transcribing the data accurately is essential but reading and manual recording of this data is a great source of error. The seamless method to add measurements to your Records on the App increases the accuracy and reliability of the data and addresses this problem.
Q. What does the Digital height measure do?
It uses ultrasonic waves to measure the length of a baby in a lying position and height of a person when standing.
Q. How does the Digital measurement work?
Ultrasonic sensors (sometimes called ultrasonic transducers), measures the distance to a target object by sending a sound pulse, above the range of human hearing (ultrasonic), then measures the time it takes for the sound echo to return. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound.
The sensor determines the distance as a measured number. Ultrasonic sensing is one of the best ways to sense proximity and detects levels with high reliability. However, soft materials which do not reflect the sonar (ultrasonic) waves may cause issues (eg. carpet surface will influence accuracy). Human errors may occur due to incorrect positioning or interference of the path of the ultrasonic wave – try adjusting the position of the person/child or the position of the measurer.
Q. Does there need to be a clear pathway for the ultrasonic sensors to work?
Yes. The sensors sends an ultrasonic pulse which travels through the air and if there is an obstacle or object in the waves path, it will affect the return wave to the sensor. Ensure firm surfaces ie. baby’s head positioned against a smooth plaster, tiled, laminate wall. Standing height – measure on an even tiled, timber or laminate surface.
Q.Why is it important to have the measure at correct angle and straight?
If the measurer is on an angle the distance for the ultrasonic wave will be affected and the accuracy of the measurement will be in doubt. The user would need to reposition and ensure the measurer is straight.
Q. What is the power source?
Double AA batteries. Secured with a safety screw and a small screwdriver is supplied in the box.
Q. Is there an age and height limit?
There is no age limit. The suggested maximum height is 2 metres.
Q. What units is the measurement in?
The measurement is recorded in centimeters.
